[Gluster-users] Very slow directory listing and high CPU usage on replicated volume

If your disks are >1TB with XFS then try mount -o inode64

This has the effect of sequential writes into the same directory being
localised next to each other (within the same allocation group). When you
skip to the next directory you will probably get a different allocation

Without this, the behaviour is to (a) stick all the inodes in the first
allocation group, and (b) to stick every file into a random allocation
group, regardless of the parent directory
